Lactose Free Milk: Is It Worth Making the Switch?

Must Try

‍Lactose free milk is a type of milk that has been specially processed to remove lactose. A natural sugar found in milk.

What if I told you lactose is good for you?!

Lactose is more than just a sugar in milk and dairy products. It is a natural and beneficial ingredient that can boost your health in many ways. Lactose is made of two simple sugars, glucose and galactose, that are linked together. Glucose is the main source of energy for your body and brain. While galactose is important for the development and function of your nervous system.

Lactose is also abundant in human breast milk, which is the perfect food for newborns and infants. It helps the growth of friendly bacteria in your gut, which can improve your digestion and immunity. Lactose also helps you absorb more calcium and other minerals from your diet, which can strengthen your bones and teeth. It is not an allergen, which means it does not cause an immune reaction in your body. However, some people may have trouble digesting lactose, because they do not produce enough of an enzyme called lactase. In this article, I will shed more light on the condition called lactose intolerance. And the available alternatives you may need to consider if you are lactose intolerant.

Lactose intolerance

Lactose intolerance is a widespread condition that affects many people around the world. It occurs when the body lacks the enzyme lactase, which is essential for digesting lactose. Without lactase, lactose cannot be broken down into simpler sugars that can be easily absorbed by the body. Instead, lactose stays in the digestive system, causing various unpleasant symptoms such as bloating, gas, diarrhea, and abdominal pain. Lactose intolerance can be primary or secondary, these are two types of lactose intolerance that have different causes and prevalence.

Primary lactose intolerance is the most common type and occurs when the production of lactase decreases naturally with age. This type of lactose intolerance is more prevalent in certain ethnic groups. Such as Asians, Africans, Native Americans, and some Europeans. It usually develops in childhood or adolescence and persists into adulthood. About 65% of the world’s population has some degree of primary lactose intolerance.

The cause of secondary lactose intolerance is an injury or disease that damages the lining of the small intestine. Such as celiac disease, inflammatory bowel disease, infection, or surgery. This type of lactose intolerance is less common and can affect people of any age or ethnicity. It may be temporary or permanent, depending on the cause and severity of the damage. We don’t know exactly the prevalence of secondary lactose intolerance. But it may affect up to 20% of people with celiac disease.

Lactose free milk and its benefits

Lactose free milk is a dairy product that has had the lactose removed. It provides a solution for individuals with lactose intolerance. It allows them to enjoy the taste and benefits of milk without the side effects associated with their inability to fully digest lactose.

Milk is a rich source of calcium, protein, vitamins, and minerals. They are essential for maintaining strong bones and a healthy body. By switching to lactose free milk, individuals can still obtain these important nutrients. But without experiencing the discomfort and digestive issues associated with lactose intolerance.

Lactose free milk also has a similar taste and texture to regular milk. This makes it a suitable replacement in recipes and beverages. This means that individuals with lactose intolerance can still enjoy their favorite dishes and drinks without compromising on flavor or texture. Additionally, it is often fortified with extra calcium and vitamins. To compensate for any potential nutrient loss during the lactose removal process.

How is lactose free milk made?

Lactose free milk is made by adding the enzyme lactase to regular milk. Lactase breaks down the lactose in milk into its simpler forms, glucose, and galactose, which are easier for the body to digest. This process is done before the milk is packaged and sold, ensuring that the lactose has been completely broken down.

There are also alternative methods of producing it such as ultrafiltration, which separates the lactose from the milk through a filtration process. This method removes the lactose without the need for adding lactase. The choice of production method may vary depending on the brand and manufacturer.

Potential drawbacks of lactose free milk

Although lactose free milk offers many benefits, there are some potential drawbacks to consider. One of the main drawbacks is the cost. Lactose free milk is generally more expensive than regular milk due to the additional processing required to remove the lactose. This can make it a less affordable option for some individuals, especially if it becomes a regular part of their diet.

Another drawback is the taste. While lactose free milk aims to mimic the taste of regular milk, some individuals may find that it has a slightly different flavor. This can be a personal preference and may take some time to get used to. Additionally, it may have a slightly sweeter taste due to the mono sugars – glucose and galactose – becoming more concentrated during the lactose removal process using the lactase enzyme.

This might sound a bit surprising to many readers but one of the drawbacks of lactose free milk is the complete absence of lactose. lactose is a natural prebiotic that can help support the development of healthy gut flora and as many lactose intolerant individuals might still be able to digest a small quantity of lactose, this means that they miss out completely on the potential health benefits of lactose.

Lastly, lactose free milk is still a dairy product, which means it may not be suitable for individuals with allergies or intolerance to milk protein. It is important to consult with a healthcare professional if you have any concerns or allergies before making the switch to lactose free milk.

Is lactose free milk worth making the switch?

Whether to switch to lactose free milk or not depends on each person’s preferences and dietary needs. Lactose free milk is a good option for people who have lactose intolerance. It has the same nutritional value and taste as regular milk, but without the lactose that causes digestive symptoms such as bloating, gas, and diarrhea. Lactose free milk allows lactose intolerant people to enjoy dairy products without discomfort and meet their calcium and protein needs.

However, lactose free milk is not the only option for lactose intolerant people. Some people may be able to tolerate small amounts of lactose, especially when eaten with other foods or in low lactose dairy products, such as yogurt and hard cheeses. Lactose may also have some benefits for the gut health and mineral absorption of lactose intolerant people if they consume it in moderation and according to their tolerance. Some countries also offer lactose-reduced milk products, which may be cheaper and more available than lactose free milk, and still suitable for some lactose intolerant people.

For people who do not have lactose intolerance, there may be no need to switch to lactose free milk. Regular milk is still a healthy and affordable choice, providing a rich source of calcium, protein, and other essential nutrients. Before making any significant changes to your diet, it is important to consider your own dietary needs and consult with a healthcare professional.

Alternatives to lactose free milk

If lactose free milk is not suitable for you or you are looking for alternatives, there are several options available.

One alternative is plant-based milk, such as almond milk, soy milk, or oat milk. These milk alternatives are naturally lactose free and provide a range of flavors and textures to suit different preferences. They are often fortified with calcium and other nutrients to make them comparable to regular milk. However, plant-based milk may have lower protein content, especially almond, rice, and coconut milk, which tends to have much less protein than cow’s milk. If you rely on plant-based milk as a source of protein, you may need to consume more of it or supplement your diet with other protein-rich foods. Plant-based milk may have added sweeteners such as sugar, and artificial or natural sweeteners, as well as additives such as carrageenan, guar gum, xanthan gum, or sodium benzoate, to enhance their consistency and shelf life.

Another alternative is lactase supplements, which can be taken before consuming dairy products to help break down lactose. These supplements provide the enzyme lactase that is lacking in individuals with lactose intolerance, allowing them to enjoy dairy products without digestive discomfort. However, it is important to note that lactase supplements may not be as effective for everyone and may not eliminate all symptoms.


Lactose free milk provides a convenient and enjoyable solution for individuals with lactose intolerance. It allows them to still enjoy the taste and benefits of milk without experiencing uncomfortable symptoms. While it offers many benefits, such as providing essential nutrients and being suitable for use in recipes, there are some potential drawbacks to consider, including cost, taste preferences, and missing out on lactose benefits.

Ultimately, the decision to switch to lactose free milk depends on the degree of intolerance, individual preferences, and dietary needs. It is important to consult with a healthcare professional if you have any concerns or allergies before making the switch. There are also alternative options available, such as low lactose milk, plant-based milk, or lactase supplements, for individuals who are unable to or prefer not to consume lactose free milk.
